Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Waiver. In accordance with Column 2 of REACH Annex IX, the soil simulation test (required in Section, 9.2.1) does not need to be conducted as direct or indirect exposure of soil is negligible.

Additional information
Waiver. In accordance with Column 2 of REACH Annex IX, the soil simulation test (required in Section, 9.2.1) does not need to be conducted as direct or indirect exposure of soil is negligible. Exposure potential is expected to be negligible since the substance is only used as a monomer to make polyurethane mouldings. There is negligible exposure to aqueous process streams during downstream use and hence also negligible emission to a sewage treatment plant. Exposure of soil is hence also considered negligible. The chemical safety assessment does not indicate any need to investigate further the degradation of the substance and its degradation products. Also, the substance’s low hydrophilicity is demonstrated by the very low log octanol-water partition coefficient (Log Kow) of 0.41 at a neutral pH indicating low adsorptive potential. Therefore, no additional degradation testing is necessary based on negligible exposure.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
